The lamp body comprises a hollow main body, a plurality of fins, a cup, a tube and a plurality of ridges. The hollow main body is connected to the lamp holder. The fins are connected between the hollow main body and the cup. A plurality of channels are defined between the fins. A hole is defined in the cup, and the tube is connected to the hole of the cup. The ridges are formed on the cup and around the tube. The light source is formed on the ridges. The light source comprises a plurality of LED elements and a plurality of circuit printed boards.

Abstract: An LED lamp includes a tube and a light bar received in the tube. The tube includes a base and a lamp window. A lengthwise first slot is defined on a center bottom of the base. The light bar includes a first surface, an opposite second surface, a first side and an opposite side. The first side and the second side are respectively coupled with the first surface and the second surface. Several light emitting diodes are mounted on at least one of the first surface or the second surface. The first side of the light bar is inserted into the first slot of the base. The second side of the light bar is close to a center bottom of the lamp window.

Abstract: A condenser lens includes a bottom surface, a top surface, and an outwardly curved side surface coupling the bottom surface and the top surface. The bottom surface defines a receiving chamber. The receiving chamber is configured to receive a light source. The top surface is inwardly depressed until reaching a reflection surface. The reflection surface is configured to substantially reflect all light received at the bottom surface. The outwardly curved side surface is configured to substantially reflect all light reflected by the reflection surface, whereby light reflected by the outwardly curved side surface is output from the top surface. The present disclosure further provides a lamp having a condenser lens.

Abstract: An illuminating device includes a circuit board, a plurality of LED (light emitting diode) elements, a first envelope with a first opening, a second envelope with a second opening and a third envelope with a third opening. The LED elements are arranged on and electrically connected with the circuit board. The first envelope covers and faces the circuit board. The second envelope covers and faces the LED elements. The third envelope covers and faces the second envelope. The second opening is coupled to the first opening to surround the LED elements and the circuit board. The third opening is coupled to the first opening to surround the LED elements, the circuit board and the second envelope.

Abstract: A circuit board for bearing a plurality of light emitting diodes includes a base and a bent portion. The bent portion extends and bends from a lateral periphery of the base. The base and the bent portion are integrally formed. An outer surface of the bent portion resists other component to embed and fix circuit board. This disclosure also discloses a light emitting diode lamp having the circuit board.

Abstract: A light emitting diode (LED) illuminating device includes a base, an LED substrate mounted on the base, at least one LED arranged on the LED substrate and an envelope. The envelope includes an open end fixed on the base, a top end opposite to the open end, and a reflection portion protruding from an inner surface of the top end and extending toward the LED substrate. A reflection layer is arranged on the reflection portion, light beams emitted by the at least one LED pass through the envelope to spread out.

Abstract: A heat-dissipating device with a base and multiple fins is described. The base has multiple grooves formed periodically thereon. Each of the fins has an end formed with a folded portion. The ends with the folded portions are thicker than the fins themselves and fixed within the grooves of the base. The fins can be made thinner than conventional ones. Hence, the number of the fins of the heat-dissipating device can be increased to enhance the heat-dissipating efficiency thereof. Furthermore, the grooves of the present invention can be made wider, so the manufacture of the present invention is easy and the overall cost is low.
